Specification of Letters Patent.

latented June 20, 1916.

To all whom it may concern Be it known that we, LEE W. BARBER and EDWINVi. WVEBB, citizens of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Side Bearings for Cars; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention has for its object to provide an improved side bearing forrailway cars; and, to such ends, generally stated, the inventionconsists of the novel devices and combinations of devices hereinafterdescribed and defined in the claims.

In the. accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view of the improved sidebearing, with some parts broken away and with some parts removed; Fig. 2is a side elevation thereof with some parts broken away, some partsshown in vertical central section, and with other parts removed; Fig. 3is a section taken on the line :0 m of Fig. 2; and Fig. i is a sectiontaken on the line r12 a? of Fig. 2.

The numerals 1 and 2 indicate, respectively, the upper section and thelower section of a housing, which is preferably made from castings, butif desired, said upper section may be a pressed steel member. The lowersection 1 of the housing has a flanged base adapted to be riveted,bolted or otherwise rigidly secured to the ends of a truck bolster. Thebody of the lower section 1 is a box-like structure cast integral withthe base and suitably ribbed. In the side walls of this box-likestructure, is formed sleeve-like seats 3 in which are mounted the endsof a pair of horizontally spaced heavy pins 4. On the intermediateportion of each pin at is loosely journaled a roller 5. The uppersurfaces of these rollers 5 are located at the same altitude and extendabove the top upper surface of the section 2 of the housing.

The base of the lower section 1 of the housing, just beloweach roller 5,is cut away at 6, so that sand and dirt may work downward out of thehousing, it being assumed, of course, that the truck bolster will havesome provision, such as a passage to permit the precipitation of thesand and dirt. Horizontal flanges 7 are integrally formed with the sidesof the lower section 1 of the housingand extend between the sleeve-likeseats 3.

The top of the upper section 2 of the housing is formed with a smoothflat bearing surface 9 and its end portions are bifurcated'to receivethe rollers 5 and the prongs thereof are fitted onto the sleeve-likeseats o. Flanges 10 are integrally formed on the sides of the uppersection 2 of the housing and rest directly upon the flanges 7. Rivets 11passed through the flanges 7 and 10 rigidly connect the upper and lowersections of the housing. It will be noted that the heads of the rivets11 are located below the top bearing surface 9. The object of the topbearing surface 9 is to provide a bear ing surface for the rollerengaging bearing surface carried by the body bolster of the car, whichnormally engages the rollers 5, in case said rollers are broken orremoved.

The sleeve-like seats 3 hold the pins 4 against lateral displacement,but are open at their ends to permit endwise displacement thereof. Tohold the pins 4 against endwise displacement, from the seats 3,depending flanges or lips 12 are integrally formed with the prongs ofthe upper section 2 of the housing, embrace the seats 3 and overlap theends of the pins 4:. It is desirable to hold the pins l againstrotation, so thatthe rollers 5 will rotate thereupon. To accom plishthis result, beveled stop lugs 13 are integrally formed with one of theside walls of the lower section 1 of the housing and extend upward, oneinto each of the seats 3, formed in the respective side wall, as bestshown in Fig. 3. Onev end of each pin l is beveled at lei. These beveledsurfaces 14 of the pins 1 engage the beveled stop lugs 12 and hold thepins t against rotation. The stop lugs 13 also prevent endwisedisplacement of the pins 4, through the seats 3 in which said stop lugsare located.

hat we claim is 1. A side bearing for cars comprising a housing made upof rigidly connected upper and lower members, said lower member having apair of axially spaced sleeve-like seats extending through the sidewalls thereof, a pin mounted in said seats and held thereby againstlateral displacement but with freedom for endwise displacement, saidupper member having flanges overlapping the ends of said pin and holdingthe same against endwise displacement, and a roller 1 on said pm.

2. Ar'sidebearing for cars comprising a housing made up of rigidlyconnected Tip-- per and lower members, said lower member havlng a pa rof axially spaced sleeve-like 1-0 seats extending through the side wallsthereof, a pin mounted in said seats and held thereby against lateraldisplacement but with freedom for endwise displacement, said uppermember having flanges overlapping the ends of said pin and holdingthe'sanle against endwise displacement, a roller on said pin, and meansfor holding said pin against rotation.

3. A side bearing for cars comprising 'a housing made up of rigidlyconnected up per and lower members, said lower member having a pair ofaxially spaced sleeve-like seats extending throughthe side wallsthereof, a pin mounted in said seats and held thereby against lateraldisplacement but with freedom for endwise displacement, said uppermember having flanges overlapplng the ends of said pm and holdlng thesame Copies of this patent 'may be obtained for five cents each,

against endwise displacement, a roller on said pin, and a stop lugextending into one of said seats with which the adjacent end of said pinengages for holding the same against rotation.

4. A side bearingfor cars comprising a housing made up of rigidlyconnected up-'- the ends of said pin and holding the same againstendwise displacement, a roller on said pin, and a beveled stop lugextending into one of said seats with which a beveled surface on theadjacent end of said pin engages for holding said pin against rotation.

In testimony whereof we affix our signa tures in presence of twowitnesses.
